was that with same power supply and woofers " same impedence yeah?

how do i do that?

im going to be ordering 2 of either amp. some questions regarding these. will the DC run happily at 0.7ohm? have there been any bench tests done on the DC Amp? which amp is more durable, and less lightly to destroy itself? my power supply is a 210 amp alternator with adjustable regulator, and 8x Hawker Gennesis batteries. with lots of 0Awg! What would you guys recommend? im preferably looking for opinions from people who have used both, but even if you have just used one, id like some feedback. Thanks guys

got my recone done, and got some more work done on the rest of it, heres how its looking now the scoop is all smoothed and ready for painting, just need my special paint to get here

got some more done to this lately. decided to put a big scoop up to take all the pressure off the tailgate and stop it flapping like mad, and an MDF roof too also some more batteries, closer to the amps so there is less resistance in the cables. its far from finished, still needs a lot of work doing on it. Pix: The start of the scoop... Scoo out to fiberglass it properly More batteries. note the messy as hell cables that are all coming out and being replaced. scoop back in temporarily and thats it for now, will ad more when i do more!

the volt meter is a good idea, might give it a go. how long do you guys play for with this sort of power? will the subs take it all day long?

nah its for the escort, and i think i found another amp 2 use.......... lets say the guy who has it now benched it @ 10krms @5ohm and i am getting another 3 of the hawkers that will be going where the bench of the back seats r now, so 7 of them plus the 180 amp alt (when i get it) also with the adjustable reg too. i was thinking about wiring in a permanent scope thing so i can see when im playing that the signal is clean What do you guys reckon?

would the level 5 take it? its either that or the saz2500. ill be using 1 per sub(got 2 subs) power supply will be 1 180amp alt and 7or so Hawker Gennesis batteries. the only problem i can see with the 3500's is my power supply. Have there been any bench tests on the DC 3k or 3.5k(cant remember what 1 it is) amps? Thanks guys

will be expensive for me to wall it, as i would have to buy another sub/amp i am considering it tho......... 3 wide in a flat wall tuned low neither can i dude, its gunna be pretty mad when i do. and especially if a wall it too

Why if it drops under 13v? I haven't heard of an amp smoking at 13v... Refer to my quotes for some info from Boon on low voltage and amp damage. i dont supose you have a link to the topic that was posted on do you? Thanks Boon first says it on the first page, then on the second gives a detailed description of the circuitry and electronics inside an amplifier and how they work. Right here: http://www.stevemeadedesigns.com/board/topic/102061-cooked-my-amp/page__hl__1419163 Thanks, thats a great read very informative.

nope, i get to a point where i think thats enough, i aint turning them up any more lol

31/32ish test frequencies are 20, 25, 33, 40 and peak, which is 36. i know playing below tuning is bad etc etc, and i dont play 20 hz tones daily, its on ocasions, and have never had any propblems with any other subs doing the same thing. and if it was down to the tone, then y did only 1 sub go???

yeah, after i heard the rattle i took it out the box and played it quietly, had about 10mm movement tops. just cause its a 20 hz tone dosent mean thats what killed it m8. and it just so happens thats 1 of the frequencys that i get tested on, so yeah i do play it loud @ 20 hz. my other (brand new) sub is fine, as well as every1 elses in the same competition format. now could you please offer some usefull info or go away

right, the coil finally stopped working on saturday night. just been playing around with the subs, and when i was playing a 20hz tone through it i could hear a rattle coming from where the spider joins the cone, and where the tinsel leads go in. this wasnt a scraping, it was a rattle, and was definately coming from the sub. i have made a video of it, just gotta wait for my bro to get back and get it on the pc and upload it. im hoping its just lose tinsel leads and can be repaired with just a new dustcap, and not a total recone.

If you were thinking of a Sundown 3500, why not email a DC dealer about a couple DC 3.5ks? They are actually pretty damn cheap for 3.5Ks. Or maybe seeing if you could get a couple of AQ 3500s. i would like the DC3500's, as i dont think there are any in this country yet, and i would love to be the 1st with them. i will make a proper decision when i have some spending money lol. could a dealer pm me with a price on a pair of 3500's please

the alt is 40A on idle, and 70A with the revs up lol. it should be charging at 14.4, but only does about 13.6/7 it is on its way out, and a m8 is sorting me out with another standard 1 cheap to get me through. i cant wait to get a proper one in there

i will do. thanks for the informative convo

upon closer inspection, the coil does work. when i connect it up, the cone will move about 5 or 6 mm. using the same speaker cables, when i connect the other coil, it moves 20 mm not exact measurements but you get the idea. any ideas what the hell is up with this?

thats on my to do list too, add a couple of fans. the amps go get pretty warm, not too hot but warm enough for my liking. i dont think id like to run any lower than .5 but if i end up getting another pair of my amps and strapping them, i may have to run 0.35 as i dont want to go as high as 1.4 i loose a lot of power doing that.

why wouldnt you recomend running at .5 ohm? if he had a 1ohm stable amp, and good power supply, run it at 2ohm daily, and 0.5 for burps in competition. as long as the amp is getting enough power it will be fine. after box rise etc it will be geting more than 0.5 any way. my amps run daily at 0.7 and are fine. not saying you are wrong/arguing with you, just asking a question i can usually tell by the question, the persons experience level and i give an answer based on that. going to half ohm means seriously pushing the limits of your equipment and you need to be ok with blowing something up. I dont think the OP is at that stage. so while battling imp rise with a low nominal load is the correct answer for some people (i was doing it myself) its not the answer for everyone. aahhhh ok cool. was just wondering is all altho im not ok with blowing anything up i still run under impedence, but keep an eger eye on volts and how hot stuff gets

Florida is a bit far for me dude, i live in London lol how hard is it to recone a sub tho? wached a few vids on youtube and the hardest bit seems to be lining up the coil. does a recone pack come with the (cant remember the name now) things to hold the coil centre? other than that seems pretty easy.... bet im wrong lol if its pretty easy i may give it a go

an spl dynamics s2000-d have 1 for each sub, and the other sub is fine. this one was purchased 2nd hand tho, so not sure how the previous owner looked after it. he had 2 up for sale, and 1 needed a recone. maybe he know this one was on its way out?

while i was playing last night, i noticed one sub was moving more than the other, and there was a funky smell...... thaught it may have been a coil, and today i think i pretty much confirmed it. now i dont have a volt meter, so i just (at very low volume) ran it at 1 coil at a time, and 1 dosent work is it recone time? or is there anything else it could be? i did put the speaker cables directly onto the tinsel leads to make sure it wasnt the terminal. it just seems a bit odd that only 1 coil went
